Title: A/d converter circuit
Inventor: SHIOZAKI YUKINORI
IPC: H03M1/18
Filed: 1990-11-27
Abstract: PURPOSE:To improve the resolution of A/D conversion without increasing the quantity of comparators for constituting the A/D converting circuit by using a subtracter and a multiplexer. CONSTITUTION:A subtracting part 6 subtracts a reference voltage generated by a reference voltage generating part 3 from the output analog signal of an S/H (Sample and Hold) part 4. A comparator 5 compares the analog signal from the S/H part 4 and the reference voltage from the reference voltage generating part 3 and outputs a digital signal, and a multiplexer 7 switches the analog signal outputted from the subtracting part 6 by the digital signal outputted from the comparator 5. Accordingly, resolution of an A/D converting circuit 11 comes to the product of resolution of voltage deciding circuits 9, 10. In such a way, the resolution of A/D conversion can be enhanced without increasing the number of comparators for constituting the A/D converting circuit 11.

Title: Knock control system
Inventor: MIZOJIRI KAZUHIKO
IPC: F02D45/00
Filed: 1988-12-24
Abstract: PURPOSE:To enable accurate detection of sensor fail by a method wherein a period, in which engine vibration is high, different from a period in which no knocking occurs is selected, and by means of a noise level prevailing during this period, detection of sensor fail is effected. CONSTITUTION:An output signal from a vibration sensor 1 to convert engine vibration into an electric signal is inputted to a comparator 3 through a bandpass filter 2. A comparing signal therefrom is inputted to a microcomputer 5 to decide the presence of knock, and the ignition timing of an igniter 8 is controlled. The noise level of an output signal from the vibration sensor 1 is calculated, and the noise level and a sensor fail threshold (value higher than a conventional threshold) are compared with each other. When the noise level is continued during a predetermined time or the predetermined number of igniting times, sensor fail is decided to occur. During decision of the sensor fail, a delay amount of an ignition timing is fixed.

Title: Brush and its using method
Inventor: YAMASHITA NOBUYUKI
IPC: H02K13/00
Filed: 1994-12-27
Abstract: PURPOSE: To significantly reduce the electric loss of a brush used in an electric motor and improve the motor efficiency by forming, in the brush providing irregular parts on the sliding surface side making contact with a commutator, a low resistance thin film layer on the whole brush surface including the irregular part. CONSTITUTION: In an electric motor brush (graphite carbonaceous) having an irregular part 7 on the sliding surface side making contact with a commutator 3 having an insulating layer 2 interposed between commutator pieces 1, silver paste is applied about 50μm in thickness to the whole brush surface including the irregular part to form a low resistance thin film layer 8. The width of the groove between the protruding parts of the irregular part 7 on the brush top end is set narrower than the width of the insulating layer 2 between the commutator pieces. Thus, an electric motor is held with high efficiency and stable rectifying performance from the initial stage of the operation to improve the brush life.

Title: Peripheral controller
Inventor: OSHIMA SHIGERU
IPC: G06F13/14
Filed: 1988-12-23
Abstract: PURPOSE:To prevent the duplication of channel numbers by writing the contents of a logical address line into an EEPROM in its own PKG when this PKG receives an access and sending an answer signal back to a bus when the coincidence is obtained between the contents of the EEPROM and the value of the logical address line. CONSTITUTION:A bus control circuit 12 checks the result of comparison carried out via a comparator 11 between the output contents received from an EEPROM 10 and the data on a logical address line 4 at input of a logical strobe signal 3. Then the circuit 12 sends an answer signal 6 back to a CPU 200 when the coincidence is obtained between the contents of the EEPROM 10 and the data on the line 4. At the same time, the control 12 outputs a start pulse to a peripheral control circuit 13 to fetch the contents of a data line 5. As a result, the CPU 200 can set its own PKG number after application of a power supply and is a working state of the PKG. Thus it is possible to eliminate the duplication of channel numbers due to a mis-setting operation of a switch.

Title: Semiconductor device
Inventor: AIGOU TAKASHI
IPC: H01L21/338
Filed: 1994-12-28
Abstract: PURPOSE: To provide an FET with a high cut-off frequency, by limiting the total capacitance of source/gate-pad capacitance and source/gate-bus-line capacitance to a given level or lower, and preventing a deterioration in high frequency caused by capacitance on the input side. CONSTITUTION: A filed effect transistor FET is formed by using GaAs/Si substrate which includes a GaAs substrate made up of a GaAs buffer layer 11 and a GaAs active layer on a silicon substrate 10. As to parasitic capacitance in the FET, the total capacitance of source/gate-pad capacitance and source/ gate-bus-line capacitance causes an increase in source/gate capacitance on the input side. In this case, the total capacitance of parasitic capacitance is made not more than 10% of the source/gate capacitance on the input side, so a decrease of cut-off frequency in high-frequency input can be prevented. The influence of parasitic capacitance caused by the pad or the gate bus-line is reduced, and the FET that is by no means inferior to an FET formed on a GaAs bulk substrate can be obtained.

Title: Formation of three-dimensional electric circuit
Inventor: SUMITA MASUJIRO
IPC: H05K1/03
Filed: 1993-12-24
Abstract: PURPOSE:To enable a micro-electric circuit to be formed by rounding at least a corner, where an electric circuit is to be formed, by sandblasting. CONSTITUTION:When a nozzle 1 is fixed to the top of an edge and etching is performed, a round recess is formed. However, when etching is performed while the nozzle 1 is in reciprocating motion to the left and right of the edge, a profile with a round recess is obtained. At this time, the same result is obtained when the workpiece itself is moved in reciprocating motion with the nozzle 1 fixed. Also, when etching is performed on a part to be etched not for the entire ridge of the edge but only on a part where an electric circuit is to be formed, it can be done by covering a part not to be etched with a resist film or a metallic mask 2. This enables circuit continuity and strength to be secured.

Title: Task scheduling system for multiprocessor
Inventor: KANEKO SEIJI
IPC: G06F9/50
Filed: 1990-11-28
Abstract: PURPOSE:To improve the efficiency of a buffer storage device by selecting a task to be executed based upon a device number and evaluation information by one processor, and when the data volume of a copy relating to a task left in an buffer storage device in the other processor is larger than a prescribed value, selecting the task by the other processor. CONSTITUTION:Respective processors 1, 2 respectively include exclusive buffer storage devices 4, 5, which are connected to a main storage device 3. At the time of selecting a task to be executed in the processor 1 e.g. from plural tasks to be processed in a computer system, the processor 1 successively reads out task control blocks in a task control block queue and selects the task to be executed by evaluation based upon processing device numbers and evaluation information. When the data volume of a copy relating to a task left in the buffer storage device 5 in the other processor 2 is larger than the previously determined prescribed value, the task is not selected by the processor, but is selected by the processor. Thus the efficiency of the buffer storage devices 4, 5 can be improved.
